The Football Association is probing a yellow card shown to an Arsenal player during a Premier League match, following allegations of suspicious betting patterns.
It comes after concerns were raised with the FA about an unusual amount of money being placed on a Gunners player being cautioned during the match.
The player in question has not been named.
An FA statement said: “The FA is aware of the matter in question and is looking into it.”
It is understood that while the governing body is looking into the matter, it is not a formal investigation at this time.
Arsenal have declined to comment.
Spot-betting allows punters to place bets on specific details in matches – such as bookings, or the number of corners – rather than the overall outcome of a game.

In September 2009, former Southampton and England midfielder Matt Le Tissier published an autobiography in which he revealed he had placed a spread bet on the timing of the first throw-in in a match he played in.
Le Tissier tried to over-hit a pass to team-mate Neil Shipperley to force a throw-in, but failed to get the ball out of play. The matter was referred to Hampshire Police but the Crown Prosecution Service elected not to pursue a case.
